TO ALL WHOM IT MAY CONCERN:

Be it known that I, D. F. HAASZ, of Philadelphia, Pennsylvania, haveinvented an improvement in Spring- Bottorns for Bedsteads; and I dohereby declare the following to be a full, clear, and exact descriptionof the same.

My invention consists of certain strips, rods, and springs, constructedand arranged as fully described hereafter, so as toiform a yielding andelastic support for a bed or mattress orcushion.

In order to enable others skilled in the art to make and apply myinvention, I will now proceed to describe its construction andoperation, reference being had to the accompanying drawing, which formsa part of this specification, and in which- Figure 1 representssuihcient of a spring-bottom for bedsteads to illustrate myimprovement..l

Figure 2, a sectional elevation on the line 1 2, iig. l; and

Figure 3, a plan view partly in section.

A is one of a series of parallel wooden strips or bars which extendacross and are connected to the frame of a bedstead or seat. In thestrips A are openings fc, in Veach of which slides a rod, a, hav-ing atits upper end a disk, b', and at the opposite sides of the stripsadjacent to each opening x are projections ce, round which are wound thecoiled portions of wire springs d of the form shown in the drawing, theinner end of each Vcoil being bent into the form of a hook which catcheson to a pin, e, on the strip A. To the outer end of each spring d islinked a rod, f, which is hooked at the lower end to one. of the bentends of a bar, 17Land on the latter bears the lower end of the rod a,the bar fitting in a recess, w,in the lower end of the rod. In the loweredge of the bar A is a recess, y, in which 4the bar h fits when theparts are in the position shown in tig. l. Owing to the peculiar mannerin whichthe rods a are suspended, they will move freely vertically withbut little friction, and form an extremely yielding and elastic supportfor the mattress or cushion which rests upon the disks ZJ. l

The above device is simple and cheap, the several parts may be readilysecured to and detached from each other, and .the springs CZ are soconstructed and arranged that they will not be liable to become weakenedby constant usage.

I claim as my invention, and desire to secure by Letters Patent- Thesprings del, linksfj', and bar i, in combination with the strap A,sliding-rod a, and disk b, or its equivalent, the whole beingconstructed, arranged, and operating substantially as and for thepurpose described.

In testimony whereof I have signed my na'me to this specication in thepresence of two subscribing witnesses.

D. F. HAASZ.
